Myeloablative Total Body Irradiation (TBI) has since long been a cornerstone of the conditioning for hematopoietic stem cell transplantation (HSCT). Currently, use of TBI is mainly indicated for high-risk hematologic malignancy with allogeneic HSCT. The aspiration to reduce acute and long-term effects has induced changes in HSCT and TBI protocols over time. Institutions have varying site-specific setups and techniques for conventional TBI. Several centers have introduced highly conformal techniques such as VMAT or TomoTherapy. Total Marrow Irradiation (TMI), Total Lymphoid Irradiation (TLI), and Total Marrow and Lymphoid Irradiation (TMLI) target the bone marrow and/or lymphoid volume while reducing doses in the remainder of the body.
While techniques may vary from center to center, several considerations regarding setup, total dose, fractionation and organ shielding are of interest to all specialists who perform TBI. The scarcity of guidelines and low number of treated patients in most centers makes international collaboration and knowledge exchange valuable.
In the 2023 TBI Symposium, international experts who have cooperated in the establishment of protocols and scientific publications will take the floor to give in-depth presentations regarding current and future perspectives for conventional and highly conformal radiotherapy techniques during myeloablative conditioning for HSCT in children and adults. The program will cover clinical, technical and biological issues and considerations that are relevant for the daily practice and ongoing strive for improvement of techniques. Moreover, there will be ample room for connection and discussion with international colleagues to exchange experiences during the daytime program and social gatherings on June 5 and 6.
The TBI symposium is of interest for radiation oncologists, medical physicists, radiotherapy technologists, hematologists and anybody with an interest in TBI. We hope to welcome you in Utrecht in June 2023!
